(SL) – The half-brother of North Korea dictator Kim Jong Un was in the busy Kuala Lumpur airport terminal heading back home to Macau on Feb. 13th when the two women approached him from behind and wiped what is believed to be a deadly nerve agent on his face.

Known as VX -a tasteless and odorless liquid with an amber-like color, it severely disrupts the body’s nervous system and is used as a nerve agent in chemical warfare.

A banned substance, authorities are trying to figure out how whoever gave the VX to the women got their hands on it; and if it came directly from North Korea Officials considering speculation is rampant that North Korea was behind the killing, particularly after Malaysia said Friday that VX had killed Kim. Experts say the oily poison was almost certainly produced in a sophisticated state weapons laboratory.

Someone also tried to break into the building where Jong Nam’s body is being held further leading to conspiracy theories that are looming.

Isolated North Korea has a long history of ordering killings of people it views as threats to its regime. Kim Jong Nam was not known to be seeking political power, but his position as eldest son of the family that has ruled North Korea since it was founded could have made him appear to be a danger.

Earlier this week, a high-level North Korean delegation arrived in Kuala Lumpur seeking custody of the body. North Korea opposed Malaysian officials even conducting an autopsy, while Malaysia has resisted giving up the body without getting DNA samples and confirmation from next of kin.

Malaysian officials have confirmed that the victim of the attack was Kim Jong Nam. North Korea, however, has identified him only as a North Korean national with a diplomatic passport bearing the name Kim Chol.

Kim Jong Nam was estranged from Kim Jong Un. He reportedly fell out of favor with their father, the late Kim Jong II, in 2001, when he was caught trying to use a fake passport to enter Japan for a visit to Tokyo Disneyland.

As for the Women, both have reportedly said they thought they were part of a prank TV show playing harmless tricks on unsuspecting passengers. Indonesian Siti Aisyah told authorities she was paid the equivalent of $90.

Siti nodded as her translator told her: “You are accused of murdering a North Korean man at the departure hall” of Kuala Lumpur International Airport

Vietnamese suspect doan Thi Huog spoke English telling the court, “I understand but I am not guilty,” after the murder charge was read. She looked briefly at the public gallery as she was led out and bowed her head.

The Pyongyang delegation is also seeking the release of a North Korean arrested in the case, 45-year-old Ri Jong Chol. Malaysia has not described his alleged role in the killing, and it was not clear if or when he could be charged.

Authorities are seeking seven other North Korean suspects, four of whom fled the country the day of Kim’s death and are believed to be back in North Korea. Others sought include the second secretary of North Korea’s embassy and an employee of North Korea’s state-owned airline, Air Koryo.

Kim Jong Nam is believed to have two sons and a daughter with two women living in Beijing and Macau.

Both women were wearing bulletproof vests as they were escorted from the court to Kajang Prison. Each faces a mandatory death sentence if convicted.
